Why You MUST Make

  • These are classic lemon bars with a shortbread crust and sweet-tart lemon custard topping.
  • Not everyone is a chocoholic, so having a few recipes with lemon is great for your dessert repertoire.
  • These lemon squares are easy to make and absolutely delicious!

Tips for Making Lemon Bars:

  • First, buy fresh lemons. You will need 1/2 cup of fresh juice. Each average lemon will provide approximately 2 tablespoons of lemon juice, so you will need at least 4 lemons. I’d buy one extra to be safe as there is a wide variation in sizes and juice production!
  • PRO-Tip: There are a couple of ways to get the maximum juice out of a lemon. First, you can roll the lemon back and forth on the counter with the palm of your hand to help break up the fibers. Also, microwaving the whole lemon for about 20 seconds may help get additional juice as well!
  • Use the food processor to make the shortbread crust. It is quicker than cutting the butter in by hand, plus makes a tender crust.
  • Par baking the crust first provides a barrier to the lemon filling plus ensures the crust will finish baking at the same time as the topping.
  • Making a lemon filling instead of a lemon curd provides a moister more flavorful burst of lemon.
  • Lining the baking dish with parchment or non-stick foil makes for easy removal and pan cleanup!
  • Let the bars cool completely before cutting to get the cleanest-looking squares.
  • Dust with powdered sugar before serving for a nice finished appearance.

Frequently Asked Questions

What Makes These Lemon Squares the BEST?

Starting from the bottom up, these bars begin with a simple, buttery shortbread crust. Nothing funky, just 3 ingredients pulsed in the food processor to make a perfect base.

Next, the combination of both lemon juice and lemon zest gives a bold citrus flavor. Note that fresh juice and zest are a must. None of the jarred lemon juice or off the rack dried lemon zest.

Adding flour to the lemon mixture thickens the filling perfectly without compromising the texture.

Having the perfect ratio of crust to filling is key, too. You need just enough crust so you can pick up these bars with your fingers as needed and a thicker layer of the lemon custard to give you that zesty lemon flavor you love!

How To Slice Lemon Bars?

For the cleanest slices, chill (or even freeze briefly) your bars first. Then use a warm knife (run under hot water, then dry it) to help the knife glide through the bars easily.

Lining the baking pan with non-stick foil or parchment allows you to easily remove a whole batch to a cutting board for easier slicing.

If you want all the bars to be the same size, use a ruler to make marks at 2-inch intervals along each side to guide you.

How Should You Store Lemon Bars?

They can be stored on the countertop at room temperature for 2-3 days, but to extend their lifespan, refrigerate them. They will be good for 4-5 days kept in the fridge
